II is 0.372 arcsec, while the median value is 0.285 arcsec. A histogram of the measured angular separations is shown in Fig. 2. The limiting magnitude of our system is currently determined by the detector properties and by the thresh- olding properties of the hardwired vector autocorrelator (VAC). The microchannel plate intensifier is showing a very strong loss of sensitivity over the region typically illumi- nated by speckle patterns, a degradation amounting to near- ly a factor of 3 decrease in sensitivity relative to the edge of the tube. The CCD itself shows a rather strong fixed pattern that correlates randomly with each event tagged by the VAC so that the noise contribution to autocorrelograms is in- creased and, in the faint limit, prohibits application of this detector in a sparse, single photon domain. We expect to replace the detector during 1989 and to immediately retire the VAC in favor of a commercially available frame-grabber board operating in conjunction with efficient software on a Fig. 2. The distribution of measured angular separations from Table PC/AT type computer. II is shown. Separations range from 0.031 to 2.91 arcsec, with mean As opportunities arose from well-observed portions of the and median values of0.372 and 0.285 arcsec, respectively, for the 1550 primary program, we obtained data for the 293 stars from measures of 1006 systems.

Asterisks indicate those stars for which new companions have been discovered, as reported in Table I. Daggers indicate known binaries, listed in Table II under their ADS designations (HR 40 = ADS 161, HR 4560 = ADS 8347).
